[PATCH 2/4] usb: ohci-s3c2410: disable controller wakeup on removal

[Myeonghun Pak]

Probe enables controller wakeup after the OHCI core marks controllers with
RemoteWakeupConnected as wakeup-capable. Removal does not undo this, so the
wakeup source can remain attached after driver unbind.

Disable controller wakeup after removing the HCD.

This issue was identified during our ongoing static-analysis research
while reviewing kernel code.
